76375afff2 revert quickSort change in commit http://code.google.com/p/bullet/source/detail?r=2527 and fix the underlying sort issue 
in VoronoiFractureDemo (store intermediate values in memory to avoid problems)
@todo: rewrite the island management to avoid sort for better performance

0daf69afb6 Add an improved way to approximate the area of the contact manifold, using 4 points instead of 3. It is switched off by default (need to check performance first), use gContactCalcArea3Points = false to enable it. Thanks to Hiroshi Matsuike for the improvement! 
Use App prefix for AppHfFluidDemo

385933b5ed Expose the multi-point perturbation algorithm for btConvexPlaneCollisionAlgorithm 
Usage:
	m_collisionConfiguration = new btDefaultCollisionConfiguration();
	m_collisionConfiguration->setPlaneConvexMultipointIterations();

It is only enabled for polyhedral convex shapes, because implicit/smooth surfaces such as spheres, cylinders, capsules and cones keep on rolling forever, due to the extra off-center contact points

1b305562be Added Pierre Terdiman's 'internal object' optimization to improve performance for separating axis tests. 
Make the winding consistent in btConvexHullComputer (and related fixes in btPolyhedralConvexShape), thanks to Ole!
Some fixes in the btPolyhedralContactClipping implementation (never report a penetration deeper than GJK/EPA found, to avoid issues due to its approximate contact normal directions)
Properly visualize btPolyhedralConvexHullShape that have a  btConvexPolyhedron (by calling initializePolyhedralFeatures() method)

9a9a4394ab fix in btParallelConstraintSolver to support double precision 
fixes in SAT/polyhedral contact clipping, avoid adding GJK contacts (the contact margin causes different contact depths)

0bef2e7363 Fixes in btContinuousConvexCollision, should fix Issue 347 
Continuous sweeps do not detect hits unless body0 and body1 penetrate more than allowedCcdPenetration.
This is to allow sliding objects (characters) where otherwise any contact would result in TOI = 0.
If objects penetrate deeper than allowedCcdPenetration at the start of the sweep, a TOI=0 is reported, unless the motion will separate the objects.

Secondly, a reportFailure method is added to CastResults, to handle failures gracefully (in case max iterations of conservative advancement is reached etc)

784e7fdb39 Added support for separating axis test for polyhedral shapes 
Added initial support for polyhedral contact clipping. 
This clipping takes a separating normal, that can be computed using either SAT or GJK/EPA.
To enable clipping, use btPolyhedralConvexShape::initializePolyhedralFeatures(); (needs to be enabled for both convex shapes)
No concave trimesh support for SAT/clipping yet. To enable SAT, see the toggle in btConvexConvexAlgorithm.
Fixes in contact normal in btGjkPairDetector. Hopefully this doesn't cause any regression (we need unit tests!)
